This one is courtesy Wouter de Kort, from his famous book. Okay, so what's the evil code here. Consider the following code and predict the output in Debug as well as Release modes. Output of the code under different configurations Isn't that weird that the output has varied in Debug and Release modes ? Well, … Continue reading Evil Code #006 : Build Configurations

Evil Code 0002 Optional Parameter Vs Method Overloading

Again one of those things which looks so simple, but could drive one mad during debugging. Much before Optional Parameters came in, C# developers used to depend on Method Overloading for mimicking Optional Parameters. Consider a scenario where both exists, what would be the output ? The output would be : The reason behind this … Continue reading Evil Code 0002 Optional Parameter Vs Method Overloading

Evil Code 0001 : Lambda and Ref/out

What would be output of following ?         static void Main(string [] args)         {             List< int> numlist = new List< int>() {1,2, 3, 4, 5, 6, 7 };             CalculateAndPrint( ref numlist);         }           public static void CalculateAndPrint( ref List< int> Num)         {             var n = Num.Where(d => d > Num[2]);               foreach ( var item in n)             {                 Console.WriteLine(item);             }         } The most obvious answer is … Continue reading Evil Code 0001 : Lambda and Ref/out
